Azure ml internal server error and 404 error

You need to delete and create the endpoint again and this should work.

Also, for Error 404, make sure that URL is correct.

The root cause of the issue:

Time-based retention policy was set on the storage account level. This immutability policy prevented Azure Machine Learning from writing log files to the workspaceblobstore, hence the 404 error when viewing any of the log file followed by InternalServerError.

Solution:

Allow protected writes to append blobs
